- the improved articulation according to the invention takes the form of an entity which has the appearance of a relatively flat and cylindrical casing or barrel.
- the two flanges are joined, for example using the crimped, welded or otherwise fixed ring in any common conventional manner, for example to the fixed flange so that the other of these two flanges and the intermediate flange can rotate there coaxially according to the axis ⁇ defined by the guiding and centering arrangement which includes the surface 120 and the sections 220 and 320.
- All the components of a joint according to the invention are made, for example, of suitable metal and / or of suitable synthetic resin, which are worked according to traditional techniques suitably adapted such as cutting, stamping, punching, drilling, molding ...
- the control device is equipped with a lever with an operating handle, wedged on the apparent shaft outside of at least one of the fixed and movable flanges, so as to be able to rotate this shaft preferably in one or other of the two opposite directions.
- a lever with the handle is usually placed within easy reach of the seat occupant, most often on one side of the seat or under it near its front edge.
- a joint according to the invention is also suitable in the case where there is no need to tilt the seat since it suffices for this not to mount the lock there and to make it integral in rotation by any technique the intermediate flange and one of the other two flanges.
- cam and cam follower control device provides a desmodromic or "positive" connection for the locked position and for the unlocked position since it is either the sole or the end of the cam which acts, either on the support or on the spout of the cam follower, respectively.
- the fixing means comprise for example threaded studs crimped in holes made in the bottoms of the fixed flange and of the mobile flange, around the central passage. It is clear that any other technique can be used and that in addition to such studs or the like it is possible to have clappers or the like to ensure immobilization in rotation of the fixed and movable flanges on the back and seat. All this is conventional and the solution adopted is chosen according to the requirements required to ensure interchangeability in particular.

Description
La présente invention concerne les sièges et a plus particulièrement pour objet une articulation à mémoire de position de réglage d'inclinaison qui est destinée à équiper un siège constitué notamment d'une assise et d'un dossier mobiles en rotation relativement l'un à l'autre selon au moins un axe.The present invention relates to seats and more particularly relates to an articulation with a tilt adjustment position memory which is intended to equip a seat consisting in particular of a seat and a backrest movable in rotation relatively to one another. '' along at least one axis.
Dans de nombreux secteurs industriels et pour de nombreux usages, on se sert de sièges constitués notamment d'une assise et d'un dossier mobiles en rotation relativement l'un à l'autre selon au moins un axe de manière à pouvoir à volonté soit incliner progressivement le dossier par rapport à l'assise pour lui donner une position de réglage choisie soit rabattre le dossier par exemple vers ou contre l'assise et inversement dans une position basculée ou dans une position dressée, respectivement.In many industrial sectors and for many uses, seats are used which consist in particular of a seat and a backrest which can move in rotation relatively to one another along at least one axis so as to be able at will either gradually tilt the backrest with respect to the seat to give it a chosen adjustment position, either fold the backrest for example towards or against the seat and vice versa in a tilted position or in an upright position, respectively.
De tels sièges sont utilisés notamment à bord des véhicules automobiles de tourisme, en particulier du type "coupé" ou "cabriolet", voire "berline" qui sont équipés de seulement deux portes latérales, une de chaque côté. De tels véhicules exigent des sièges avant qui soient à la fois soit inclinables à volonté au gré de leurs occupants pour leur confort, soit escamotables notamment par rabattement du dossier vers l'assise pour faciliter l'accès à ce qui se trouve à l'arrière du siège.Such seats are used in particular on board motor vehicles, in particular of the "coupé" or "cabriolet" or even "sedan" type which are equipped with only two side doors, one on each side. Such vehicles require front seats which are both either reclining at will at the option of their occupants for their comfort, or retractable in particular by folding the backrest towards the seat to facilitate access to what is at the rear. from the headquarters.
Des solutions d'articulation pour sièges de véhicules automobiles qui autorisent un réglage progressif, continu ou discontinu, de l'inclinaison du dossier par rapport à l'assise sont par exemple exposées dans les documents FR 2 463 596 et FR 2 541 950 et 2 547 778.Articulation solutions for motor vehicle seats which allow progressive, continuous or discontinuous adjustment of the inclination of the backrest relative to the seat are for example set out in documents FR 2 463 596 and FR 2 541 950 and 2 547,778.
Des solutions d'articulation qui permettent un rabattement du dossier vers l'assise sont par exemple exposées dans les documents FR 2 642 377 et FR 93 15 598. Toutes ces solutions présentent l'inconvénient d'être encombrantes, de nécessiter des constituants supplémentaires par rapport à une articulation plus classique utilisée à bord des véhicules berline à quatre portes latérales, deux par côté.Articulation solutions which allow the backrest to be folded back towards the seat are for example exposed in the documents FR 2 642 377 and FR 93 15 598. All these solutions have the drawback of being bulky, of requiring additional components compared to a more conventional articulation used on board saloon vehicles with four side doors, two per side.
Un inconvénient majeur des articulations complexes qui permettent à la fois un réglage de l'inclinaison du dossier et un rabattement du dossier, réside dans le fait que lors du relèvement du dossier préalablement rabattu pour le faire passer de sa position basculée à sa position dressée, le dossier ne retrouve pas systématiquement la position choisie de réglage de l'inclinaison qu'il occupait précédemment avant rabattement que ce soit par la conception même de l'articulation ou que ce soit par suite d'une fausse manoeuvre de l'utilisateur. Il faut alors procéder à un nouveau réglage ou à une retouche du réglage du dossier pour lui redonner sa position initiale. Une telle opération est fastidieuse et s'impose pourtant lorsque le siège en cause est celui du conducteur.A major drawback of complex articulations which allow both an adjustment of the inclination of the backrest and a folding of the backrest, resides in the fact that during the raising of the previously folded backrest to make it pass from its tilted position to its upright position, the backrest does not systematically find the chosen position for adjusting the inclination that it previously occupied before being folded down, whether by the very design of the articulation or whether it is as a result of a false maneuver by the user. It is then necessary to make a new adjustment or a touch-up of the adjustment of the backrest to restore it to its initial position. Such an operation is tedious and is nevertheless essential when the seat in question is that of the driver.
L'invention a pour but de remédier à la plupart des inconvénients brièvement énumérés précédemment à l'aide d'une articulation pour siège d'une grande simplicité, monobloc, d'encombrement réduit et qui comprend sous un boîtier commun de préférence en forme de barillet pratiquement cylindrique, les moyens nécessaires au réglage de l'inclinaison progressive du dossier et les moyens nécessaires au rabattement du dossier, et avec en outre une mémoire de la position de réglage en inclinaison du dossier afin que celle-ci soit immédiatement retrouvée et reprise lorsqu'on redresse le dossier préalablement rabattu.The object of the invention is to remedy most of the drawbacks briefly listed above with the aid of a very simple, monobloc seat joint, of reduced bulk and which comprises under a common housing preferably in the form of practically cylindrical barrel, the means necessary for the adjustment of the progressive inclination of the backrest and the means necessary for the folding down of the backrest, and with in addition a memory of the position for adjusting the inclination of the backrest so that it is immediately found and resumed when straightening the previously folded back.
Cette articulation, de préférence modulaire, peut être construite avec les moyens de rabattement ou sans ceux-ci, ce qui permet de l'utiliser indifféremment pour des sièges de véhicules à une ou deux portes latérales, par côté.This articulation, preferably modular, can be constructed with the folding means or without these, which makes it possible to use it indifferently for vehicle seats with one or two side doors, per side.

L'alvéole est délimité par une paroi 211 latérale axiale et par un fond 212 transpercé d'un passage 2120 destiné à servir de palier ou à recevoir un palier comme indiqué à propos du flasque fixe. De préférence, ce flasque mobile est muni d'une collerette 22 avec une tranche 220 cylindrique circulaire, coaxiale à l'axe Δ, de manière à constituer un agencement de guidage et de centrage comme indiqué à propos du flasque fixe.The
Le flasque intermédiaire 30 est destiné à être placé dans le logement délimité par les alvéoles 11 et 21 des flasques fixes 10 et mobile 20, respectivement. Le flasque intermédiaire 30 se présente à la manière d'un disque 300 avec des faces 301 et 302 opposées ainsi qu'avec une tranche 320 cylindrique circulaire, coaxiale à l'axe Δ de manière à constituer un agencement de guidage et de centrage comme indiqué à propos des flasques fixe et mobile. La face 301 est placée en regard du flasque fixe 10 et la face 302 est placée en regard du flasque mobile 20. Ce disque est transpercé d'un orifice 303 central.The
Le mécanisme de réglage 40 de l'inclinaison est associé au flasque intermédiaire 30 et coopère avec le flasque fixe 10. Ce mécanisme est mobile entre une position enclenchée dans laquelle les flasques fixe 10 et intermédiaire 30 sont accouplés en rotation, et une position déclenchée dans laquelle les flasques fixe 10 et intermédiaire 30 sont désaccouplés en rotation pour autoriser un réglage de l'inclinaison. Ce mécanisme 40 comprend une denture 41 portée par la paroi latérale axiale 111 de l'alvéole 11 du flasque fixe 10 et au moins un "grain" ou loqueteau 43 denté mobile destiné à coopérer avec la denture 41. Le grain denté 43 est monté mobile sur l'une des faces 301, 302 du flasque intermédiaire 30 à l'aide d'un guide 430. Ce guide 430 comprend notamment une portée 431 de préférence en arc de cylindre circulaire concave sur le grain denté 43 et un pivot 432 de préférence en arc de cylindre circulaire convexe sur la face en question du flasque intermédiaire.The
Le verrou de blocage 50 de rabattement est associé au flasque intermédiaire 30 et coopère avec le flasque mobile 20. Ce verrou est mobile entre une position enclenchée dans laquelle les flasques mobile 20 et intermédiaire 30 sont accouplés en rotation et une position déclenchée dans laquelle les flasques mobile 20 et intermédiaire 30 sont relativement désaccouplés en rotation pour autoriser un rabattement et inversement. Ce verrou 50 comprend au moins une gâche 52 portée par la paroi latérale axiale 211 de l'alvéole 21 du flasque mobile 20, et au moins un pêne 53 destiné à coopérer avec la gâche 52 et monté mobile sur l'une des faces 301, 302 du flasque intermédiaire 30 à l'aide d'un guide 530. La gâche 52 a la configuration d'une encoche en créneau dont l'embrasure est constituée d'une entaille 521 et dont le merlon est constitué d'une butée 522 de préférence en arc de cercle concave. Le pêne 53 a la configuration d'un loquet avec un flanc 530 de préférence en arc de cercle convexe et un épaulement 5301 pratiquement radial destinés à coopérer avec l'entaille 521 ou la butée 522. Ce guide 530 comprend une portée 531 de préférence en arc de cylindre circulaire concave sur le pêne 53 et un pivot 532 de préférence en arc de cylindre circulaire convexe sur la face en question du flasque intermédiaire.The
Comme cela apparaîtra par la suite, le mécanisme 40 et le verrou 50 opèrent dans des plans propres particuliers qui sont parallèles et perpendiculaires à l'axe de rotation Δ. De la sorte, le mécanisme et le verrou peuvent être situés d'un même côté d'une face du flasque intermédiaire ou chacun d'eux est situé d'un côté d'une face opposée du flasque intermédiaire.As will appear later, the
La commande mobile 60 comprend au moins deux couples de came 61 et contre-came 62 dont la première 61 a un profil 610 avec une semelle 6101 et un bout 6102 et dont la seconde 62 a un appui 621 et un dégagement 622 avec un bec 623, ainsi qu'un arbre 63 apte à entraîner les cames 61. Pour les raisons qui apparaîtront par la suite semelle et appui, d'une part, et bout et bec, d'autre part, sont destinés à coopérer les uns avec les autres pour la position verrouillée ou la position déverrouillée. L'un de ces couples est destiné à agir sur le mécanisme 40 et l'autre de ces couples est destiné à agir sur le verrou 50. La came 61 d'un couple est portée de préférence par un bras 611 radial monté sur l'arbre 63 alors que la contre-came 62 de ce couple est portée par le grain denté 43 ou par le pêne 53. S'il y a lieu, des plots ou similaires portés par le flasque intermédiaire contribuent au guidage des cames. Comme on le comprendra par la suite, il y autant de couples de came et contre-came qu'il y a, d'une part, de pênes pour le verrou et, d'autre part, de grains dentés pour le mécanisme. L'arbre 63 est coaxial à l'axe Δ et est monté sur les parties des flasques fixe et mobile qui servent de palier ou aptes à en recevoir. Cet arbre est apparent à l'extérieur de l'un des flasques fixe et mobile au moins pour les raisons qui apparaîtront par la suite. Une sollicitation élastique 64 agit sur chacune des cames 61 de manière que chaque semelle 6101 soit normalement au contact de l'appui 621 correspondant de la contre-came 62 du couple considéré, afin de tendre à placer et maintenir le mécanisme 40 et le verrou 50 en position verrouillée par mise en prise des grains dentés et denture, d'une part, et des pênes et gâches, d'autre part. La sollicitation élastique 64 comprend par exemple un ressort du type de ceux utilisés pour les "pinces à linge", dont une branche est ancrée de toute manière appropriée par exemple sur la came et dont l'autre est ancrée de même sur le flasque intermédiaire.The
La ou les sollicitations élastiques peuvent être assurées à l'aide d'un ressort unique ou de deux ressorts distincts. Si l'on utilise un ressort unique ou deux ressorts séparés situés d'un même côté du flasque intermédiaire alors que les cames sont situées sur des côtés opposés de ce flasque, il faut prévoir une branche sur le ressort et une lumière dans le flasque intermédiaire que traverse cette branche pour agir. Les formes données à une semelle et appui d'un couple sont telles que sous l'action de la sollicitation élastique un effort pratiquement radial centrifuge est développé.The elastic stress (es) can be provided using a single spring or two separate springs. If a single spring or two separate springs located on the same side of the intermediate flange are used while the cams are located on opposite sides of this flange, a branch must be provided on the spring and a light in the intermediate flange through which this branch passes to act. The shapes given to a sole and support of a couple are such that under the action of elastic stress a practically radial centrifugal force is developed.
L'arbre 63 présente deux méplats 631 symétriques et la came 61 présente un évidement 612 central en secteur avec deux appuis 613 symétriques destinés à coopérer chacun avec un des méplats 631 pour les raisons qui apparaîtront par la suite. Les appuis 613 ont une configuration en "papillon" ou similaire et ménagent de préférence un certain jeu avec les méplats pour les raisons qui apparaîtront par la suite.The
La sécurité 70 est constituée par la butée 522 de la gâche 52 qui est portée par le flasque mobile 20 et par un flanc 530 du pêne 53 qui est porté par le flasque intermédiaire 30. La sécurité est destinée à condamner le verrou en position déclenchée comme on le comprendra par la suite.The
L'articulation perfectionnée selon l'invention se présente en une entité qui a l'aspect d'un boîtier ou d'un barillet relativement plat et cylindrique. Les deux flasques sont réunis par exemple à l'aide de l'anneau serti, soudé ou autrement fixé de toute manière classique courante par exemple au flasque fixe de manière que l'autre de ces deux flasques et le flasque intermédiaire puissent y tourner coaxialement selon l'axe Δ défini par l'agencement de guidage et de centrage qui comprend la surface 120 et les tranches 220 et 320.The improved articulation according to the invention takes the form of an entity which has the appearance of a relatively flat and cylindrical casing or barrel. The two flanges are joined, for example using the crimped, welded or otherwise fixed ring in any common conventional manner, for example to the fixed flange so that the other of these two flanges and the intermediate flange can rotate there coaxially according to the axis Δ defined by the guiding and centering arrangement which includes the
Tout ce qui précède est clairement illustré sur les figures du dessin annexé auxquelles il y a lieu de se reporter.All of the above is clearly illustrated in the figures of the appended drawing to which reference should be made.
Tous les constituants d'une articulation selon l'invention sont faits par exemple en métal approprié et/ou en résine synthétique appropriée, qui sont ouvrés selon des techniques traditionnelles convenablement adaptées tels que la découpe, l'estampage, le poinçonnage, le perçage, le moulage ....All the components of a joint according to the invention are made, for example, of suitable metal and / or of suitable synthetic resin, which are worked according to traditional techniques suitably adapted such as cutting, stamping, punching, drilling, molding ...
Tous les constituants d'une articulation selon l'invention sont réunis, montés et assemblés comme cela ressort clairement notamment de l'examen des figures du dessin.All the components of a joint according to the invention are assembled, mounted and assembled as is clear, in particular from the examination of the figures in the drawing.
On en expliquera maintenant le fonctionnement.We will now explain how it works.
On rappellera que, comme il est classique, le dispositif de commande est équipé d'un levier avec une poignée de manoeuvre, calé sur l'arbre apparent à l'extérieur de l'un au moins des flasques fixe et mobile, de manière à pouvoir faire tourner cet arbre de préférence dans l'un ou l'autre des deux sens opposés. Un tel levier avec la poignée est habituellement placé à portée de main de l'occupant du siège, le plus souvent sur un côté de l'assise ou sous celle-ci à proximité de son bord antérieur.It will be recalled that, as is conventional, the control device is equipped with a lever with an operating handle, wedged on the apparent shaft outside of at least one of the fixed and movable flanges, so as to be able to rotate this shaft preferably in one or other of the two opposite directions. Such a lever with the handle is usually placed within easy reach of the seat occupant, most often on one side of the seat or under it near its front edge.
On supposera qu'à l'état initial le mécanisme de réglage de l'inclinaison et le verrou de blocage de rabattement sont en position enclenchée où la semelle de la came repose contre l'appui de la contre-came. On voit alors de ce fait que et le flasque fixe et le flasque mobile sont accouplés au flasque intermédiaire. Dans cette condition l'articulation est "rigide", aucune rotation selon l'axe Δ n'est possible.It will be assumed that in the initial state the mechanism for adjusting the inclination and the tilting locking bolt are in the engaged position where the sole of the cam rests against the support of the cam follower. It is therefore seen from this fact that both the fixed flange and the movable flange are coupled to the intermediate flange. In this condition the joint is "rigid", no rotation along the axis Δ is possible.
Si maintenant on agit sur le levier lié à l'arbre dans le sens approprié (sens horaire sur la Figure 3) à l'encontre de la sollicitation élastique, l'un au moins des méplats de l'arbre rencontre au moins un appui de l'évidement de la came après résorption du jeu et la fait tourner et ainsi sépare d'abord sa semelle de l'appui pour la placer à l'aplomb du dégagement, puis le bout rencontre le bec : le ou les grains dentés initialement en prise avec la denture s'en sépare(nt) rapidement. On a fait passer le mécanisme de sa position enclenchée à sa position déclenchée. Le flasque intermédiaire est désaccouplé du flasque fixe mais demeure accouplé au flasque mobile. On observera à ce propos que si les sollicitations élastiques sont assurées par un ressort unique, du fait du montage adopté pour ce ressort, l'effort qu'il exerce sur le ou les pênes croît ce qui renforce sa mise en prise dans la gâche et améliore l'enclenchement du verrou. On peut donc modifier l'inclinaison du dossier relativement à l'assise et lui donner la valeur recherchée. Le relâchement de la poignée du levier fait que les grains reviennent en prise avec la denture sous l'action de la came rappelée par la sollicitation élastique, de manière que le mécanisme reprenne sa position enclenchée. L'articulation a repris une situation "rigide".If we now act on the lever linked to the shaft in the appropriate direction (clockwise in Figure 3) against the elastic stress, at least one of the flats of the shaft meets at least one support of the recess of the cam after absorption of the game and makes it rotate and thus first separates its sole from the support to place it in line with the clearance, then the end meets the spout: the toothed grain (s) initially engaged with the teeth separates quickly. The mechanism was moved from its engaged position to its triggered position. The intermediate flange is uncoupled from the fixed flange but remains coupled to the movable flange. It will be observed in this connection that if the elastic stresses are ensured by a single spring, due to the assembly adopted for this spring, the force which it exerts on the bolt or bolts increases, which reinforces its engagement in the keeper and improves lock engagement. We can therefore modify the inclination of the backrest relative to the seat and give it the desired value. The loosening of the handle of the lever causes the grains to come back into engagement with the teeth under the action of the cam recalled by the elastic stress, so that the mechanism returns to its engaged position. The articulation took over a "rigid" situation.
Si l'on agit maintenant sur le levier lié à l'arbre dans le sens opposé (sens anti-horaire sur la Figure 4), c'est au moins un autre des méplats de l'arbre qui rencontre au moins un appui correspondant de l'évidement de l'autre came après résorption du jeu et la fait tourner et ainsi sépare d'abord sa semelle de l'appui pour la placer à l'aplomb du dégagement puis le bout rencontre le bec : le ou les pêne(s) du verrou initialement en prise avec la gâche s'en sépare(nt) rapidement. On a fait passer le verrou de sa position enclenchée à sa position déclenchée. Le flasque intermédiaire est désaccouplé du flasque mobile mais demeure accouplé au flasque fixe. Ce qui a été exposé auparavant à propos de l'effort développé par la sollicitation élastique vaut aussi maintenant pour le mécanisme. On peut donc rabattre le dossier vers l'assise. On observa qu'au cours de cette opération, la sécurité joue son rôle puisque le flanc du pêne reste en regard de la butée de la gâche et glisse contre elle et lui interdit de revenir en prise avec celle-ci : on maintient de la sorte le verrou condamné en position déclenchée. Du fait de la présence et de l'action de la sécurité, il n'est pas nécessaire d'agir en permanence sur la poignée du levier de la commande. Pour redresser le dossier, il suffit de le faire basculer dans le sens opposé : il retrouve alors à coup sûr son inclinaison initiale puisque celle-ci est fixée par la position du pêne porté par le flasque intermédiaire qui est resté accouplé au flasque fixe. S'il y a lieu, le rappel en position dressée du dossier est obtenu ou aidé par un ressort spécial compensateur associé au siège, comme il est connu.If we now act on the lever linked to the shaft in the opposite direction (anti-clockwise in Figure 4), it is at least one other of the flats of the shaft which meets at least one corresponding support of the recess of the other cam after absorption of the game and rotates it and thus first separates its sole from the support to place it above the clearance then the end meets the beak: the bolt (s) ) of the latch initially engaged with the strike separates (s) quickly. The lock was moved from its engaged position to its released position. The intermediate flange is uncoupled from the movable flange but remains coupled to the fixed flange. What has been explained previously with regard to the force developed by elastic stress also applies now to the mechanism. We can therefore fold the backrest towards the seat. It was observed that during this operation, security plays its role since the side of the bolt remains opposite the stop of the strike and slides against it and prohibits it from coming back into engagement with it: in this way it maintains the locked lock in the released position. Due to the presence and action of safety, it is not necessary to act permanently on the handle of the control lever. To straighten the backrest, it suffices to tilt it in the opposite direction: it then finds its initial inclination for sure since it is fixed by the position of the bolt carried by the intermediate flange which has remained coupled to the fixed flange. If necessary, the return to the upright position of the backrest is obtained or assisted by a special compensating spring associated with the seat, as is known.
On observera aussi qu'au cours d'un rabattement ou d'un redressement du dossier et lorsque le levier lié à l'arbre est laissé libre, le ou les méplats de l'arbre opposés à celui ou ceux ayant servi à la manoeuvre de déclenchement du verrou, sous l'action de la sollicitation élastique sont ou viennent au contact du ou des appuis correspondant de l'évidement de la came du verrou dont la semelle est emprisonnée dans le dégagement de la contre-came du pêne dont le flanc est lui même maintenu appliqué contre la butée de la gâche. Du fait d'une telle chaîne cinématique, la sécurité rend impossible tout déverrouillage du mécanisme de réglage de l'inclinaison par manoeuvre volontaire ou fortuite du levier lié à l'arbre, ce dernier ne pouvant tourner dans le sens opposé d'un angle suffisant pour autoriser le désengagement des grains dentés de la denture du flasque fixe. La mémoire de la position de réglage de l'inclinaison du dossier est ainsi toujours sauvegardée.It will also be observed that during a folding or straightening of the backrest and when the lever linked to the shaft is left free, the flat part (s) of the shaft opposite to that or those having been used for the maneuver of triggering of the bolt, under the action of elastic stress, are or come into contact with the corresponding support or supports of the recess of the cam of the bolt, the sole of which is trapped in the release of the cam follower of the bolt, the side of which is itself kept applied against the striker stop. Due to such a kinematic chain, security makes it impossible to unlock the tilt adjustment mechanism by voluntary or accidental operation of the lever linked to the shaft, the latter being unable to rotate in the opposite direction by a sufficient angle. to authorize the disengagement of the toothed grains from the teeth of the fixed flange. The memory of the backrest adjustment position is therefore always saved.
On notera, par contre, qu'avec une telle chaîne cinématique, lorsque l'arbre occupe sa position de repos, normale, où il est maintenu de toute manière appropriée, on peut agir sur le mécanisme de réglage de l'inclinaison sans entrave du verrou de blocage de rabattement ou, inversement, on peut agir sur le verrou de blocage de rabattement sans entrave du mécanisme de réglage de l'inclinaison.It will be noted, on the other hand, that with such a kinematic chain, when the shaft occupies its normal rest position, where it is held in any suitable manner, one can act on the adjustment mechanism of the unhindered tilting of the tilting locking latch or, conversely, one can act on the unhindered folding locking latch of the tilt adjustment mechanism.
Dans ce qui précède, on a supposé une commande unique qui opère dans deux sens opposés. Il est clair qu'on peut utiliser aussi une commande multiple, par exemple dédoublée, l'une pour le réglage de l'inclinaison et l'autre pour le rabattement. Dans un tel cas, comme il est connu, la poignée de manoeuvre est dédoublée et celle destinée au rabattement est située par exemple sur le côté latéral extérieur du dossier. Il suffit alors d'utiliser une timonerie convenable, rigide articulée ou souple de tout type approprié, qui relie cette poignée de manoeuvre à l'arbre de la commande mobile ou à la came appropriée.In the above, we have assumed a single command which operates in two opposite directions. It is clear that one can also use a multiple control, for example split, one for the adjustment of the inclination and the other for the folding. In such a case, as is known, the operating handle is split and that intended for the folding is located for example on the external lateral side of the backrest. It then suffices to use a suitable linkage, rigid articulated or flexible of any suitable type, which connects this operating handle to the shaft of the mobile control or to the appropriate cam.
On a supposé qu'une seule articulation selon l'invention était utilisée par siège. Il est clair qu'on peut utiliser deux articulations par siège, une située de chaque côté : il faut alors dans ce cas que la commande agisse simultanément sur les deux articulations. Pour ce faire, il suffit par exemple de prolonger l'arbre pour qu'il s'étende transversalement d'un côté à l'autre du siège. De même, si la commande au lieu d'être unique avec deux sens opposés de fonctionnement est double, on peut faire en sorte qu'elle soit coaxiale à l'axe Δ.It was assumed that only one joint according to the invention was used per seat. It is clear that two joints can be used per seat, one located on each side: in this case, the control must act simultaneously on the two joints. To do this, it suffices for example to extend the shaft so that it extends transversely from one side to the other of the seat. Similarly, if the control instead of being single with two opposite directions of operation is double, we can make it coaxial with the axis Δ.
Du fait de sa conception modulaire, une articulation selon l'invention convient aussi au cas où on n'a pas besoin de basculer le siège puisqu'il suffit pour cela de ne pas y monter le verrou et de rendre solidaire en rotation par toute technique appropriée le flasque intermédiaire et l'un des deux autres flasques.Due to its modular design, a joint according to the invention is also suitable in the case where there is no need to tilt the seat since it suffices for this not to mount the lock there and to make it integral in rotation by any technique the intermediate flange and one of the other two flanges.
Dans ce qui précède, on a supposé que le mécanisme avait deux grains dentés diamétralement opposés et que le verrou avait de même deux pênes et deux gâches diamétralement opposés. Il est clair que les nombres de grains et de pênes-gâches peuvent être différents l'un de l'autre et que la situation des grains et pênes-gâches peut être modifiée.In the foregoing, it was assumed that the mechanism had two diametrically opposite toothed grains and that the lock likewise had two bolts and two strikes diametrically opposite. It is clear that the numbers of grains and latch bolts can be different from each other and that the situation of grains and latch bolts can be changed.
Dans ce qui précède, on a supposé que les grains du mécanisme et les pênes du verrou étaient animés de mouvements de basculement. Il est clair qu'en utilisant des guides convenablement adaptés, le(s) grain(s) denté(s) et le(s) pêne(s) peuvent avoir des déplacements rectilignes.In the foregoing, it has been assumed that the grains of the mechanism and the bolts of the bolt were driven by tilting movements. It is clear that by using suitably adapted guides, the toothed grain (s) and the bolt (s) can have rectilinear displacements.
On observera que le dispositif de commande à came et contre-came assure une liaison desmodromique ou "positive" pour la mise en position verrouillée et pour la mise en position déverrouillée puisque c'est soit la semelle soit le bout de la came qui agit, soit sur l'appui soit sur le bec de la contre came, respectivement.It will be observed that the cam and cam follower control device provides a desmodromic or "positive" connection for the locked position and for the unlocked position since it is either the sole or the end of the cam which acts, either on the support or on the spout of the cam follower, respectively.
Dans la description qui précède, on a supposé que c'est le flasque fixe qui porte la denture intérieure et qui assure le guidage en rotation du flasque intermédiaire et du flasque mobile. Il est clair que ces rôles peuvent être inversés entre flasque fixe et flasque mobile. Il en est de même du flasque fixe et du flasque mobile qui peuvent être intervertis, l'un et l'autre pouvant être montés indifféremment sur le dossier ou sur l'assise. Dans le mode de réalisation illustré, on a supposé que c'est le flasque fixe qui est monté sur l'assise et que c'est le flasque mobile qui est monté sur le dossier.In the above description, it has been assumed that it is the fixed flange which carries the internal toothing and which ensures the rotation guidance of the intermediate flange and of the movable flange. It is clear that these roles can be reversed between fixed flange and mobile flange. It is the same for the fixed flange and the mobile flange which can be reversed, both of which can be mounted either on the backrest or on the seat. In the illustrated embodiment, it has been assumed that it is the fixed flange which is mounted on the seat and that it is the movable flange which is mounted on the backrest.
Dans la description qui précède, on a supposé que c'est le flasque fixe qui est munie d'une surface de guidage et de centrage, étagée ou non, qui coopère avec les tranches du flasque mobile et du flasque intermédiaire pour former l'agencement de guidage et de centrage. Il est clair que toute autre solution peut être adoptée; il suffit que l'un des flasques serve des références aux deux autres pour définir l'axe de rotation.In the above description, it has been assumed that it is the fixed flange which is provided with a guiding and centering surface, stepped or not, which cooperates with the edges of the movable flange and of the intermediate flange to form the arrangement. guiding and centering. It is clear that any other solution can be adopted; it suffices that one of the flanges serves as references to the other two to define the axis of rotation.
Dans la description qui précède, on a supposé que les grains du mécanisme de réglage de l'inclinaison étaient montés sur le flasque intermédiaire et la denture de celui-ci était portée par le flasque fixe, il est clair que la disposition inverse peut être retenue et adoptée. Il en est de même des pênes et gâches du verrou qui au lieu d'être respectivement montés sur le flasque intermédiaire et être portées par le flasque mobile peuvent être disposées à l'inverse. On notera qu'on peut aussi utiliser pour partie la solution illustrée et pour partie la solution inverse de celle-ci.In the above description, it has been assumed that the grains of the tilt adjustment mechanism were mounted on the intermediate flange and the toothing thereof was carried by the fixed flange, it is clear that the reverse arrangement can be retained and adopted. The same applies to the bolts and strikes of the bolt which, instead of being respectively mounted on the intermediate flange and being carried by the movable flange, can be arranged in reverse. It will be noted that one can also partly use the illustrated solution and partly the inverse solution thereof.
Les moyens de fixation comprennent par exemple des goujons taraudés sertis dans des trous ménagés dans les fonds du flasque fixe et du flasque mobile, autour du passage central. Il est clair que toute autre technique peut être utilisée et que outre de tels goujons ou similaires on peut disposer de clabots ou analogues pour assurer une immobilisation en rotation des flasques fixe et mobile sur les dossier et assise. Tout ceci est classique et la solution adoptée est choisie en fonction des prescriptions requises pour assurer notamment l'interchangeabilité.The fixing means comprise for example threaded studs crimped in holes made in the bottoms of the fixed flange and of the mobile flange, around the central passage. It is clear that any other technique can be used and that in addition to such studs or the like it is possible to have clappers or the like to ensure immobilization in rotation of the fixed and movable flanges on the back and seat. All this is conventional and the solution adopted is chosen according to the requirements required to ensure interchangeability in particular.
Ce qui précède met bien en lumière les particularités distinctives de l'invention, l'intérêt qu'elle offre et les avantages qu'elle procure.The above clearly highlights the distinctive features of the invention, the interest it offers and the advantages it provides.
